2023 KIA SORENTO Complaints

I purchased a new 2023 Kia Sorento in February 2023 from Ken Garff Kia Avondale. Since shortly after purchase, the vehicle has experienced repeated electrical and mechanical failures that substantially impair safety. In July 2023, the vehicle began displaying flashing lights, dashboard error messages, and system malfunctions while driving, despite no collision or visible damage. The air conditioning system malfunctioned and blew hot air even when turned off. The dealership stated a front sensor was “damaged” and not warranty-covered, despite no visible damage, and verbally indicated that many other customers were experiencing similar issues. Repairs took nearly four months, during which Kia Corporate engineers were involved. The issue persisted despite repairs. In December 2024, the vehicle began displaying repeated transmission system error warnings, often within the first 5–10 minutes of driving, causing significant loss of speed and drivability. After multiple service visits, the vehicle required a full transmission replacement in July/August 2025 under warranty. Despite this repair, the same transmission errors returned in December 2025. More critically, the vehicle then experienced multiple sudden and complete electrical shutdowns without warning, including: Shutting off entirely while stopped at a red light, requiring a jump start All screens going black and the vehicle failing to restart Restarting only after being left parked for several minutes These events occurred without any battery or system warning indicators and created a serious safety risk, including risk of being stranded or disabled in traffic. The issues have been documented with photos, videos, repair records, and written communications. Due to the ongoing and dangerous nature of these failures, I am reporting this as a vehicle safety defect.

Upon starting the vehicle, it flashed several warning lights that were not on the day before. Including popping codes up on the infotainment system and urging me to schedule a service with KIA. Upon looking up the codes it states HVAC issue, when calling to dealership to schedule a service for it (while it is still barely under warranty) they let me know it might not be covered. That’s when I found out there is a recall only for certain VIN #’s for the exact same issue. My car won’t even drive because the electrical system is being affected. Windshield wipers going crazy, lights not working, AC/heat not working, the emergency braking system braking out of nowhere, the lane departure pulling the wheel while driving without cause. I don’t even feel safe driving the vehicle anymore. Kia needs to have a recall on this that alerts the vehicles owners because I had no clue that there was a potential fire hazard due to faulty wiring.

Was driving on Dallas North Toll way when my vehicle lost acceleration. Had to pull over and engine started smoking and lit a flame under the hood. Car is now at Clay Cooley Kia in Irving, TX. Car has been there for over two weeks and I still have no answers or information regarding the plan to fix it. Major dealership delay and all they keep saying is “Waiting on a Kia Engineer to come out but we don't have a date.”

I have been calling the nearest Kia dealership to have this recall fixed since September 2025 and there has been no remedy since. We do not feel safe using the vehicle due to the recall involving a fire hazard due to HVAC wiring. We have a family that needs the vehicle and its been 3 months with no remedy and no estimated date of when remedy will be available, so remedy for recall is indefinite. We would like Kia to repurchase the vehicle or assist in auto monthly payments, as we are paying for a vehicle that we cannot use. We have kids and do not feel comfortable driving in this vehicle. We use this vehicle to help work and recall has impacted us financially. Below are details of the recall as we are trying to get Kia to help with: Manufacturer Recall Number SC351 There is no remedy for this safety recall ***REMEDY IS NOT AVAILABLE YET*** KIA AMERICA, INC. IS RECALLING CERTAIN 2021-2023 SORENTO VEHICLES. THE HEATING, VENTILATION, AND AIR CONDITIONING (HVAC) BLOWER MOTOR WIRING HARNESS MAY BE INADEQUATE, WHICH CAN RESULT IN A FIRE. Safety Risk A FIRE INCREASES THE RISK OF INJURY.

Incident #1: [XXX] The vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 MPH with oncoming traffic from both the East and West as I was turning West from a North Bound Road. On coming traffic was traveling between 45 and 50 MPH. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 MPH speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the Kia of Round Rock dealership November 17th. The car remained at Kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to Kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [XXX] Vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (No traffic was visible.) The car would not accelerate more than 20 MPR, the speed limit was 55 MPH. For the 1.5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 MPH. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2023 Kia Sorento. The contact stated that while attempting to activate the HVAC system, there was an abnormal burning plastic odor inside the vehicle. There was no warning light illuminated. The vehicle was to an independent mechanic who diagnosed the vehicle and determined that the blower motor relay had short circuited and needed to be replaced. The vehicle was not repaired; however, the contact performed a repair based on guidance from the mechanic. The contact stated that the vehicle was repaired, but the failure with the blower motor relay reoccurred. The contact recently received notification of NHTSA Campaign Number: 25V649000 (Electrical System, Visibility). The contact related the failures to the recall. The contact called a local dealer and was advised that the remedy was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not informed of the failure. The failure mileage was approximately 48,000.

While driving my 2023 Sorento plug-in hybrid a msg appeared that Charging Stopped Check Cable. When you stop the car and try to drive it will not go into any gear, msg says Shifting Conditions Not Met and Unplug Vehicle to Start and the wheels are locked up (E-brake) and needs a tow truck with dollies in order to load. This happened in the middle of the Highway and it’s happened FOUR times. By the time the dealer looks at it, the problem has cleared and does not show any codes. It’s not easy to reproduce since it just happens sometimes with the warning and sometimes no warning. The dealer tells me nothing is wrong with the car yet someone could get killed by being rear ended. I’ve tried for 4 months to get a Kia Field Tech out to diagnose but just keep getting lip service from Kia Customer “I don’t “ Care. I feel the car is to dangerous to drive and have refused to pick up from dealer until they fix it.

Check engine light on. Rear defrost doesn't work. Auto stop/start not working. Cruise control not working. Vehicle shuts off sometimes at stand still and have to put in neutral or park and push Start button. Engine looses power while driving. Check rear cross traffic, check tire pressure monitoring system, check lane departure warning system, check speed limit system, check lane keeping assist, check forward safety system lights are cycling on the front screen and warning ?? signs pinging. Vehicle has been inspected 3 times at a local KIA DEALERSHIP. 1st in 4/2025, 2nd 6/2025 3rd time 10/2025. Module was replaced and 2 days later same issue so Vehicle will be going back a 4th time. No warnings before issues started. Sometimes it does it for hours and sometimes it's back to normal.

Around 35,000 miles the vehicles fuel pump, relay assembly, and smart junction box failed and left my wife stranded. Kia took about 7+ days to diagnose and repair.

On 8 occasions, while driving on a highway, the emergency lights started to flash out of no where and the driver could not accelerate. The driver had to find a way to pull over and turn the car off and then restart the car. The car was taken in 3 times and checks were run but no codes showed up. The third time the car was brought in, the mechanic agreed to drive it until the problem could be reproduced. The car was driven for 70 miles but it could not be reproduced. The mechanics were informed that it happened every 300-500 miles and the car had not been driven enough. The mechanics said it was running as designed. Our safety and everyone on the road was put at risk if we could not get over to a shoulder.
